Notifications on Downloading

In the notification interface, (the one with mail, realms ect), people could see what mods they downloaded onto the game. It would tell them warnings and errors, not only in the pack, but why certain packs weren't able to download. Eg: "Duplicate packs detected" "Device doesn't support ray casting". It could also be an option to save mods / addons externally. Saving time, so you won't have to re download the same pack if you re install the game. Favourites addons would be nice too.
